Option to Generate enum for UPPER_CASE

[harish1094]

How can I configure the generation of an enum with UPPER_CASE keys?

"TaskType": {
                "title": "TaskType",
                "enum": [
                    "test_type_1",
                    "test_type_2",
                    "test_type_3", 
                    "invalid_type",
                ],
                "type": "string",
                "description": "An enumeration."
            }

The generated out is :

export type TaskType =
    (typeof TaskType)[keyof typeof TaskType];

export const TaskType = {
    test_type_1: "test_type_1",
    test_type_2: "test_type_2",
    test_type_3: "test_type_3",
    invalid: "invalid"
} as const;

Expected enum:

export type TaskType =
    (typeof TaskType)[keyof typeof TaskType];

export const TaskType = {
    TEST_TYPE_1: "test_type_1",
    TEST_TYPE_2: "test_type_2",
    TEST_TYPE_3: "test_type_3",
    INVALID: "invalid"
} as const;

This can be done by adding

"x-enumNames":[
  "TEST_TYPE_1",
  "TEST_TYPE_2",
  "TEST_TYPE_3",
  "INVALID"
]

Either directly in your spec, or by mutating the input at generation time

@AllieJonsson ,
Could you please share a link to an example document or provide an example of how I can achieve this?

I think i got it

Will play with it now! Thanks,

You can also check out https://orval.dev/reference/configuration/input#transformer
This lets you access the parsed openapi object and can modify it. So you can check all properties in all schemas and if there are any enums, you can add the x-enumNames property to it

This works well; however, it would be helpful to have an option to configure the enum naming convention to use uppercase. Otherwise, we have to handle it in the transformer, which becomes quite involved for nested OpenAPI schemas.

https://orval.dev/reference/configuration/output#namingconvention-property-keys

override: {
        namingConvention: {
          enum: 'upper',   -----------------------------------------> To uppar case enums
        },
 }
